[Fot] GT6 Connecting rods

[Barr, Scott]

Right - my problem has always been being really confident that I am measuring the same bolt the second time.  I tried once marking them with different colors of nail polish.  That didn't work at all, for reasons that will be obvious to some.  I'll come up with some way of doing it.  Replacing them at intervals is painfully expensive and probably needless.  I replace them when my gut tells me that they don't feel right when I'm torqueing them - like I really expect to get that final torque wrench click, but instead I get another 90 degrees of twist on the wrench before I get the click.  I need a better system than that  :-)

that's what the GT6 has.  TR6 with the stroker crank may be different.
I agree with you, they seem tiny, but I'e been running them for six years with no issues.  Carillo tells me they are re-usable, though I never thought to record the installed measurements and check against them a year or two later.
What I will do when I pull the bottom end apart in a week or two is to measure the installed length and then remeasure once disassembled.  If they "shrink" as much as the stretch dimension used for installation, they should still be good, i.e., they have not been stretched beyond the elastic range.

Do the TR6/GT6 Carrillos have the same teeny-tiny little rod bolts that the Carrillos for my 1500 Spit do?  I think they're 1/4", with a torque spec of something like 18 lb/ft?  I just don't like those.  Granted, never had one fail, but I also have been replacing them every once in a while at something like $37 per bolt.  You're supposed to inspect them frequently by checking to see whether they have stretched at all, but I've never come up with a really reliable way of comparing the length of one particular rod bolt upon disassembly against its length at assembly.

The most cost effective thing you can do to your engine is spend a lot of money on a set of Carrillo's!
Mine are about 16 years old.

Hi Gents.
  I am looking for feedback on the MaxSpeeding connecting rods for GT6.  Can't afford Carrillos and I'm hoping these are good. Also am still searching for an aluminum flywheel without having something custom made. and would like input on what type of clutch to use as well . Lets call it a race car for the sake of argument....
                               Thanks.  P.J.
